Abstract

This paper proposes the out-of-step (OOS) protection system, which operation principle is based on combination of two approaches: equal area criterion, implemented in time domain, is used for generators first swing stability assessment and generation sources electromotive forces (emf) vectors angle control is used for multi swing instability detection. The paper focuses on possibilities of practical implementation of the above mentioned approaches within real time operating OOS protection system. Protection system structure and principles of operation addressed in the paper.
采用时域等面积判据的失步保护
本文提出了一种失步保护系统,其工作原理基于两种方法的结合:采用时域实现的等面积判据进行发电机首摆稳定性评估,采用发电源电动势矢量角度控制进行多摆稳定性检测。本文重点讨论了上述方法在实时运行的OOS保护系统中实际实施的可能性。文中论述了保护系统的结构和工作原理。
